Can you get the libvirt QEMU args from the log file
/var/log/libvirt/qemu/XPHome.log
so we can compare them to the args your custom script
used. There will probably be some minor difference that's
confusing windows
LC_ALL=C
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
HOME=/home/dh USER=root LOGNAME=root QEMU_AUDIO_DRV=none /usr/bin/kvm -S
-M pc -m 512 -smp 1 -name XPHome -uuid
26e5de74-0841-c4b3-4cc1-e0df0f93cb31 -monitor
unix:/var/lib/libvirt/qemu/XPHome.monitor,server,nowait -localtime
-no-acpi -boot c -drive file=/media/XP/vdisk.img,if=ide,index=0,boot=on
-drive file=/media/XP/vdisk1.img,if=ide,index=1 -drive
file=/dev/cdrom,if=ide,media=cdrom,index=2 -net
nic,macaddr=54:52:00:7a:ee:01,vlan=0,name=nic.0 -net
tap,fd=17,vlan=0,name=tap.0 -serial pty -parallel none -usb -usbdevice
tablet -vnc 127.0.0.1:0 -k en-us -vga cirrus -soundhw es1370
char device redirected to /dev/pts/6
Running this command in a terminal i get
TUNGETIFF ioctl() failed: Bad file descriptor
TUNSETOFFLOAD ioctl() failed: Bad file descriptor
and VM is *NOT* starting!
There is no tap interface but a virbr2. Anyway, it's the same for Linux
VMs -I checked in logs- and they start.
Thanks for your support.
